PLANE.

SPECIFICATION forming' part of Letters Patent No. 600,767, dated March15, 1898.

Application filed August 5, 1897.

.To aZZ whom it may concern:

Be it known that I, JOHN BRANDELL, of \Valpole, in the county ofCheshire and State of New Hampshire, have invented certain new anduseful Improvements in Planes; and I do hereby declare the following tobe a full, clear, andexact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention is an improvement in planes, and relates more especiallyto rabbetingplanes, the object of the same being to provide one that canbe readily adjusted to increase and diminish the Width of the rabbet orgroove, and includes a guide for determining the depth of said grooveand also certain devices for adjusting the bits, all as will behereinafterfully set forth, and specifically pointed out in the appendedclaims.

In the accompanying drawings, forming part of this specification, Figure1 is a side elevation of a rabbeting-plane constructed in accordancewith my invention. Fig. 2 is a View looking at the lower edge of theplane. Fig. 3 is an end elevation. Fig. 4 is a detail View of one of thesections of the plane re.- moved, including the parts carried thereby.Fig. 5 is a similar view of the other section of the plane. Fig. 6 is aside elevation of part of section 1, showing the gage-plate. Fig. 7 isan end view of gage-plate.

Referring more particularly to the drawings, 1 and 2 designate the twosections of the plane which form the sides thereof and are connected bypins 3, which extend from one section through openings therefor in theother section, the parts being held adjustable with respect to eachother by the set-screws 4., carried by the section 2 and engaging thepins which project from the section 1. The pins are each provided with ascale, for a purpose hereinafter set forth.

The inner sides of the sections 1 and 2 of the plane are hollowed out,the section 1 presenting an inclined rib 5, upon which bears a bit 6,having teeth '7, by which it is connected to an elbow-lever 8, pivotedupon a bearing-pin 9, supported at one end by a bracket 10, while itsother end is let into the section. The lower or cutting edge of the bitis adapted to be projected below the rib 5, the section having a lateralprojection 11, the surforcing its opposite end against the bit.

face of which is curved, as shown, to guide the shavings out of theplane. The elbowlever, which is connected to the bit, as hereinbeforedescribed, is operated by a block 12, mounted upon a screw 13, hearingat its lower end in a post 14 and extending through the upper part ofthe section 1, where it is provided with a knob or milled wheel 15. Theconnection between the sliding block and lever is by means of aprojection 16 on the block engaging the bifurcated end of the lever. Theblock is prevented from turning upon the screw by bearing against theinner side of the section 1, and it will be observed that when the saidscrew is turned the bit will be raised or lowered to adjust the same.

The bit is securely clamped in position after.

being adjusted by means of a clamp consisting of the parts 17 and 18,one of which bears against the upper part of the bit, while the otherbears against the lower part thereof, the said clamp being pivoted upona bearingscrew 19, supported at one end by a bracket 20. The parts ormembers of the clamp are forced upon the bit by means of a screw 21engaging a threaded aperture in the project ing end of one part andbearing upon the'projecting end of the other part, serving to force thelatter directly against the bit, while drawing up upon the other part ofthe clamp in It will be understood, of course, that before adj ustingthe bit the clamp is released, .and by the particular construction andarrangement described a minute adjustment can be secured, the upper partof the bit being of a width to fit within the opening thereof andproperly dispose the cutting edge with respect to the edge of the plane.

The section 2 of the plane carries mechanism for adjusting the bit'whichis similar in construction to that hereinbefore described, with theexception that the bit 22 is given further bearing-surfaces to preventlateral movement, and to this end a casting 23 is secured to the rib 24,forming one of the bear.

ings for said bit, the casting having projectin g members supporting thepivot-pins of the mechanism. The bit carried by this section is solocated with respect to the bit of the other section as to be locatedbehind the same when the two sections are placed together.

By providing the plane with two sections movable to and from each otherand having each section carry abit the width of a groove to be cut bythe plane can be increased or diminished by moving said sections to andfrom each other, the adjustment being held by thumb-screws, which engagethe connectingpins. In connection with the two bits each section isprovided on its outer side with a cutting-blade 25, adjustable by havinga slot through which a retaining-screw passes.

Upon one side of the plane is mounted a gage-plate 26, adjustable withrespect to the edge of the plane by means of a thumb-screw 27 passingthrough a slot 28 therein and engaging a threaded aperture in the plane,gagemarks being provided, as shown, to indicate the extent of theadjustment, while the straight-edge of the gage-plate is maintainedparallel with the edge of the plane by forming a rib 29 upon the innerside of the plate, which slides within a recess therefor in the plane.This gage-plate is for the purpose of determining the depth of therabbet or groove.

I also provide the plane with a longitudinal guide-strip 30, connectedto stems or pins 31, which slide within openings therefor in the side ofthe plane, the said guide-strip being held by thumb-screws 32, whichengage the stems. When the guide-strip is projected below the bottom ofthe plane and held by the thumb-screws referred to, said strip may beadjusted inwardly under the body of. the stock by screws carried by thestrip and engaging threaded apertures in heads 33, formed at the outerends of the pins, the screws rotatably engaging the strip at their innerends and bearing at their opposite or outer ends in brackets 34,extending from the strip, the screws being held against longitudinalmovement with respect to the strip and its brackets. When theguide-strip is extended below the edge of the plane, it will assist informing a rabbet by bearing against the edge of the lumber or work. Informing a groove the guide-strip is slipped up out of the way, lyingsnugly against the longitudinal shoulder formed by the enlarged upperportion of the section 1 of the plane.

Having thus described the invention, what is claimed as new is 1. Arabbeting-plane comprising two sections, means for adjusting saidsections to and from each other, and bits carried by each section, thebit of one section overlapping and being located in the rear of the bitof the other section, substantially as shown and for the purpose setforth.

2. A plane comprising two sections, pins carried by one section andextending through openings therefor in the other section, screws forholding the adjustment of the movable section, and bits carried by eachsection, the bit in one section being located in the rear of andoverlapping the bit in the other section, substantially as shown anddescribed.

3. A plane for the purpose set forth, comprising two sections adjustableto and from each other, overlapping bits carried by the sections andlocated one in front of the other, a gage-plate adjustable verticallyupon one section, and a guidestrip attached to the i other section,substantially as shown and described.

4. A plane comprislng two sections ad ustj able to and from each other,overlapping bits carried by the sections and located one in front of theother, a gage-plate vertically adjustable upon one of the sections, aguidestrip connected to the other section by pins,

and set-screws engaging the pins, substantially as shown and described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
